The correct answer is D. To acknowledge where you found a source
Explanation:
In writing and especially academical writing, the term "credit a source" refers to acknowledging an external source or author and where these were found especially when you summarize, cite or use in any way the information of an external source or author. This is especially important because in this way you show you are supporting ideas with other authors but also because you are giving the credit to the person who wrote the source and acknowledging it was not created by you. According to style manuals, you should credit the source during the text in in-text citations and at the end of it with a cited works list. Considering this, it can be concluded to credit a source mainly means to acknowledge where you found a source.
